Abstract
The utility model relates to an aluminium electrolytic capacitor which comprises a core, an aluminium casing, guide tinsel strips and a cover plate. The core is disposed in the aluminium casing and sealed by the cover plate. The guide tinsel strips are riveted joint with the cover plate in a punching and riveted turning manner. According to the aluminium electrolytic capacitor, the cover plate is riveted joint with the guide tinsel strips in a punching and riveted turning manner, so that contact resistance is better controlled to be from 0.3 mOmega to 0.4 mOmega with a fine contacting property, the early failure of a product, caused by contact failure or open circuit, is prevented, and using requirements about the reliability of the aluminium electrolytic capacitor are better satisfied for a welding machine, a UPS power supply, a frequency converter and other devices.
Description
[technical field]
The utility model relates to a kind of aluminium electrolytic capacitor, relates in particular to the syndeton of leading chaff and cover plate is carried out improved aluminium electrolytic capacitor.
[background technology]
At present, what the connected mode of leading chaff and cover plate of big capacity aluminium electrolytic capacitor mainly adopted is the riveted joint mode, and it punches leading on the chaff specifically exactly, is enclosed within then on the rivet of cover plate to press together again.Owing to lead chaff and the cover plate rivet circumference has certain interval, lead chaff and the rivet contact area is very little, therefore, this kind riveted the riveted joint resistance of mode at 0.7m Ω～1m Ω.When contact resistance was bigger than normal, directly phenomenon was exactly that the electrical quantity loss is big, in the use, led chaff for a long time through big electric current, the heating oxidation of riveted joint contact site, and contact resistance continues to increase, and causes capacitor to lose efficacy.
, social demand amount increasingly mature along with device fabrication technology such as DC welder, frequency converter, ups powers also increases sharply; Its quality is had higher requirement; The quality requirement of the aluminium electrolytic capacitor that in these equipment, uses is also higher; Therefore, existing aluminium electrolytic capacitor is difficult to satisfy industrialized demand.
In view of above drawback, be necessary to provide a kind of improved aluminium electrolytic capacitor to overcome above-mentioned defective in fact.
[utility model content]
The purpose of the utility model is exactly that the spy provides a kind of aluminium electrolytic capacitor that reduces contact resistance in order to address the deficiencies of the prior art.
To achieve these goals, the utility model adopts following technical scheme: a kind of aluminium electrolytic capacitor, and it comprises fuse, aluminum hull, leads chaff and cover plate; Fuse is packed in the aluminum hull; And, wherein, describedly adopt punching to turn over the riveting riveted way when leading the riveted joint of chaff and cover plate by said cover plate for sealing.
Preferably, the said punching riveted holes that turns over riveting is the magic flower shape.
Preferably, described magic flower is shaped as rhombus.
Preferably, the described aluminium washer that is equipped with when leading the riveted joint of chaff and cover plate.
Compared with prior art; The utility model aluminium electrolytic capacitor uses punching to turn over the riveting riveted joint through cover plate with leading when chaff is riveted; Control contact resistance well at 0.3m Ω～0.4m Ω; Form the excellent contact characteristic, the product early failure of avoiding loose contact or open circuit to cause satisfies the instructions for use of these equipment of welding machine, ups power and frequency converter to the aluminium electrolytic capacitor reliability better.
[description of drawings]
Fig. 1 is the fuse schematic perspective view of the utility model aluminium electrolytic capacitor;
Fig. 2 is the riveted structure sketch map of leading chaff and cover plate of the utility model aluminium electrolytic capacitor.
[embodiment]
Please refer to Fig. 1, shown in 2, the utility model aluminium electrolytic capacitor, it comprises fuse 20, aluminum hull (not shown), leads chaff 14 and cover plate 21; Fuse 20 is packed in the aluminum hull; And by said cover plate 21 sealings, wherein, described leading when chaff 14 is riveted with cover plate 21 adopts punching to turn over the riveting riveted way.
The riveted holes 40 that riveting is turned in said punching is the magic flower shape, and in the utility model, described magic flower is shaped as rhombus.In order further to reduce the contact resistance of leading chaff 14 and cover plate 21, aforesaid leading also is equipped with aluminium washer 15 when chaff 14 is riveted with cover plate 21.
The utility model aluminium electrolytic capacitor; When riveting, chaff 14 use punching to turn over the riveting riveted joint with leading through cover plate 21; Fine control contact resistance is at 0.3～0.4m Ω; Form the excellent contact characteristic, the product early failure of avoiding loose contact or open circuit to cause better meets the requirement of these equipment of welding machine and frequency converter to product reliability.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
Claims (4)
1. aluminium electrolytic capacitor, it comprises fuse, aluminum hull, leads chaff and cover plate, and fuse is packed in the aluminum hull, and by said cover plate for sealing, it is characterized in that: describedly adopt punching to turn over the riveting riveted way when leading chaff and cover plate riveted joint.
2. aluminium electrolytic capacitor as claimed in claim 1 is characterized in that: the riveted holes that riveting is turned in said punching is the magic flower shape.
3. aluminium electrolytic capacitor as claimed in claim 1 is characterized in that: described magic flower is shaped as rhombus.
